Prevalence of headache in a representative sample of the population in a French department (Haute-Vienne-Limousin).

In 1986-1987, a neuroepidemiologic survey was undertaken to study the prevalence of the most frequently encountered neurologic disorders, and in particular headache, in a representative sample of the population in the Haute-Vienne Department (Limousin). A door-to-door survey was made using a protocol developed by the W.H.

[A neuro-epidemiologic survey in a Limousin town].

One characteristic of the Limousin district is the raised average age of its population. Given the growing average age found in France and the ensuing potential problems, it was thought useful to undertake a neuro-epidemiological study of the distribution of neurological diseases in this region. The initial step involved checking the techniques to be used and the form of questionnaire relevant to this type of study.
